Thank you for sharing. I am still not convinced that I want to go back to checking duplicate ID in a separate validating routine. The only thing I have against this method is that it requires for me to create this method and to maintain it. I am trying to downsize my application as much as possible (read: I am lazy <g>); down to just two methods: Start() and Finish() <bg>
